[zeromq-dev] High latency performance

[Martin Sustrik]

Hi Steve,

Yes, we are aware of the fact. Actually, we have a guy here who wrote 
such a bulk-transfer implementation (over IP). However, it the issue is 
not at the top of our priorities at moment - the priorities now are 
making 0MQ dynamic (rewiring of the messaging infrastructure on the fly 
rather than having it preconfigured) and multicast.
